406 agencies here work on storefront performance — the time between a tap and a usable page. Speed work has a bad reputation because a lot of it is sold against a score rather than against revenue, and the two come apart more often than the pitch admits. Done properly it is one of the few technical changes with a direct, measurable effect on conversion.

On most ecommerce stores the platform is not the problem. The problem is what has been added on top: analytics and ad tags, a reviews widget, a chat launcher, a pop-up tool, a personalisation script, each loading its own copy of a library and each blocking something.
The second cause is images — uncompressed hero art, product photography served at four times its display size, and a carousel that loads all eight slides on page load. Between third-party scripts and images you have accounted for the majority of real-world slowness on storefronts.
A synthetic performance score is a lab measurement on a simulated device. It is useful as a diagnostic and worthless as a goal, and chasing it produces genuinely harmful changes — deferring scripts that the page needs, lazy-loading the main product image, stripping a tool the marketing team depends on.
Ask instead for field data: what real visitors on real devices experience, which the platform’s own analytics and Search Console both report. If an agency’s proposal quotes only a lab score, ask what it expects to happen to the field numbers, and to conversion.
A focused pass — images, scripts, obvious blocking resources — is commonly $1,500–$5,000 and is where most of the available gain sits. Deeper work involving theme architecture, critical CSS and third-party replacement runs $6,000–$20,000. Ongoing monitoring so that the gains do not erode is usually folded into a maintenance retainer rather than sold separately.
